stm32/boards: Optimise flash and RAM allocation for L4 boards. Optimisations are: - Remove FLASH_ISR section since devices with a small flash sector erase size don't need special FLASH_ISR handling. This reduces flash image by approx 1.5k. - Make SRAM2 contiguous with SRAM1 where possible. - Simplify configuration of 2k RAM buffer used for flash filesystem. RAM changes with this commit: - L432: stack 6k -> 10k, bss + heap 42k -> 52k - L476: stack 16k -> 30k, bss + heap 80k -> 96k - L496: stack 206k -> 16k, bss + heap 112k -> 302k
